[ale] Recovering PV/LVG without /etc/lvm/archive/file.vg

[David Jackson]

The subject says it.  I was installing a new drive and installing a fresh
OS onto the new drive, then transporting the old files over to the new
drive and OS (ie, /home/dsj)

I had booted from an archlinux ISO, was doing a manual partition.  But then
I made a boo boo with the new Logical Volume Group and wanted to blow it
away to start over.

My new system was on nvme1n1 and I blew away the PV and LV info for nvme0n1
which contained the PV/LV  info for all my previous data.  Very sad senior
moment!

Now, since I booted from an arch ISO usb stick, the /etc/lvm/archive files
were in volatile memory, so I don't have a copy of them.  When I load up my
new system, which I eventually installed just fine (I'm writing this email
from that system), everything works great.  But I'd like to recover the old
system (that's probably still on nvme0n1 in the second partition, When I
boot from the new system on nvme1n1, I can look in /dev/disk/by-uuid/ and
see the old PV for nvme0n1 uuid I think:
2f1aede8-a033-4ec4-8c9f-290d7a7c3458

But there's no record for LVs or PVs on nvme0n1 anywhere in
/etc/lvm/archive.

Also, whenever I install Arch, I use a script that auto creates the same PV
and LV specs on the target drive.  The partition sizes won't have changed.

(Pretty much all the googling I've read assumes that a /etc/lvm/archive/
filename.vg exists somewhere. )

Is there any way I can restore the PV/LVG info on nvme0n1 with what I have
available?  Without the archive file?

Thanks!

Dave
